ball mill optimisation using smart fill-level control + fuzzy logic

ball mill optimisation using smart fill-level control + fuzzy logic

A sophisticated and well developed expert system should be easy to use and able to be maintained by the plant personnel. The times when remote experts need to frequently visit the plant for adjustments should be history.

A modern high-level control system allows plant operators to create and modify individual plant control loops via simple graphical tools and logic blocks. By this I do not mean set-point corrections but adding new instrumentation into the control loop and changing logical combinations. This includes new parameters like new fuel types in the combustion or the change from manual input parameters to continuous measurement signals.

The modular and open control software Smart-Control developed by KIMA Echtzeitsysteme considers such demands. It has found success in single and two-chamber ball mills (including central discharge) for raw meal, slag, coal and, of course, cement. The system can also control roller presses that are installed before the mill and separators. It is sold under the name MillMaster.

MillMaster comes with a multitude of function blocks that are assembled to a control group in a special programme called Control Designer. The intuitive user interface offers clear visualisation, is flexible and easy to learn. It was designed to offer process engineers that have no programming skills the opportunity to generate the control logic and adapt/manipulate it by themselves without the need of external support. Pre-defined functions and structures are simply created via drag-and-drop from a large catalogue of functions, helping operators to focus on the essentials. A huge library of existing structures gives, for most applications, complete solutions that can be further adapted by limit value and set point adjustments.

To smooth rapidly-varying process instrumentation signals for control purposes such digital filters compare to traditional ones in that they do not have a delay time. A classical filter would smooth the signals but would always have a delay time. This can be a killer in situations where, for example, in-situ measurements and process leading values are used in control loops.

Besides highly-sophisticated digital filters, the MillMaster system contains predictive models that can predict trends into the future. So called soft-sensors can be generated, which use multi-dimensional input vectors. This groups together significant process data to determine the outcome of longer timeframe processes, minutes or even hours in advance. This model prediction is a very useful tool for complex phenomena in nonlinear processes. It should be noted that the control methodology is distinct from model predictive control (MPC) but instead uses MPC to calculate future trends in the control loop as soft sensor information.

Each controller is only as good as its instrument for the targeted value and each grinding process is only efficient at an optimum mill capacity. The classical strategies for controlling a ball mill all influence the efficiency of the grinding process indirectly. Imagine the following set of parameters: Fresh material = constant; Reject material = constant; Total feed = constant. Such information gives the operator an impression that the process is very constant, but this is not the case. All of these parameters tend to oscillate significantly. This can be measured using a precise fill-level measurement.

For this reason KIMA decided to develop a filllevel measurement called SmartFill, which is based on structure-borne sound. Highly reproducible and stable signals give the separate fill levels of chambers 1 and 2 separately, offering high-level control systems a new source of fundamental information. Consequently the leading cement producing companies in the world have implemented or recommended the use of SmartFills electronic ears in their in-house expert systems.

KIMA uses the optimal filling of the mill as the main control parameter. This allows the grinding process to become very stable, which allows unexpected disturbances to be accommodated more easily. The main variable parameter is the hardness of the material to be ground, which influences the time it must be held within the mill. Only the time the material spends in the ball mill itself (Tmill) is not known and definitely varies with the grindability. It is thus logical that the fresh feed into the mill should be adjusted accordingly and be used to keep the level inside the mill constant.

Compared to classical proportional integral derivative (PID) controllers the fuzzy components in expert systems like KIMA Es MillMaster and SmartFill systems can compensate for signal drift that occurs as a result of wear in various parts of the process. Other technologies are all installed away from the original source of interest, i.e.: the mill body.

Microphones as well as vibration sensors that measure the variation of sound or vibrations in the bearing foundations are all indirect and failure-sensitive sources of raw information. A microphone that listens can be very sensitive to other mills, motors or gearboxes nearby, meaning that the vibrations of motors, wearing sprockets from drives or similar can disturb vibration analysis. It is no secret that these types of system must be re-calibrated, very often on a monthly basis.

With a constant fill level inside of the one or two mill chambers the optimum production volume is reached. Keeping these levels constant also secures a more constant product quality due to the particle size distribution becoming narrower. Another logical effect is the reduced wear of liners and balls which was reported by HeidelbergCement, Dyckerhoff (Buzzi Unicem), LafargeHolcim and other producers.

It is not surprising that, when it comes to certain guarantees, OEMs of grinding plants consider using SmartFill in their projects. To secure constant product quality and constantly high production for their customers in greenfield or modernisation projects, the measurement system with the sensor box mounted directly on the mill body is considered right from the first specification.

electronic ear | kana electromechs

Electronic Ear is useful for Control & Regulation of Ball Mills, using the grinding frequency signal for optimizing the Mill Output. It consists of an acoustic signal receiver (Microphone Unit / Sound Sensor) and specially constructed indicating & interpreting electronic circuit (Control Unit). Depending on the height of the material bed, the grinding media inside the Ball Mill causes a characteristic noise.

In case of high material bed (max. filling level), there is hollow grinding sound (low volume & low grinding frequency), whereas for low material bed (min. filling level), there is high pitched sound (high volume & high grinding frequency). This characteristic of grinding frequency is used to develop an output signal representing mill filling level, which can be used for regulation of the mill feed and / or for digital

Construction: The Electronic Ear comprises of two parts viz. Microphone Unit (Sound Sensor) & Control Unit. The Microphone Unit comprises of a sturdy adjustable Bracket which permits radial and axial movement of the sound sensor, to suit the mounting requirement. Terminals are provided at the back, for termination of the signal cable. The Microphone Unit is to be connected to the Control Unit through a high quality single core shielded cable & it is to be mounted as near as possible to the jacket of the mill. Mounting stand is to be fabricated at site.

Precise control needs precise measurement. In comparison with microphone-based systems and vibration sensors on bearings, SMARTFILL does not conflict with other sound and signal sources. In contrast to all existing classical methods of ball mills fill level measurement SMARTFILL is the only system, which measures the sound directly where it occurs: on the mill shell. The structure-born sound sensor only receives the signal directly on the mill body itself. SMARTFILL is operated in buildings with 16 mills, side-by-side without any interference between the measurement systems. The signals from SMARTFILL can and should be used as set-points in an advanced controller.

electronic ear / ball mill level indicator, - kana electromechs, pune | id: 1383215948

The Electronic Ear is specially developed for control and regulation of Ball Mills, using the grinding sound frequency signal for optimizing the Mill output. According to the material bed height, the grinding media causes a characteristic noise. In case of high material bed i.e. maximum filling level, there is a hollow grinding sound low grinding frequency. Whereas for low material bed i.e. minimum filling level, there is a high-pitched sound high grinding frequency. This characteristic of grinding frequency is sensed through Sound Sensor and the output of the Sensor is used to develop an output mA signal representing Mill filling level. This signal can be used for regulation of the feeding of the Mill and or for digital indication of the Mill filling leve

classifying and ball mill production line - alpa powder technology

ALPA enjoys a high reputation in more than 100 countries and regions around the world. With its high-quality products and services, it has won the trust of many well-known brand companies around the world.

The product particle size control is flexible, special design is adopted to reduce noise and emission. Automatic control, easy to operate. According to the scale of investment, it provides personalized customized scheme and provides value-added services.

According to different materials and application industries, the production capacity and particle size range will be different. Please contact our engineers to customize the equipment for you. Our experts will contact you within 6 hours to discuss your needs for machine and processes.

After coarse crushing, the material is fed into the ball mill through a controllable feeding device. The grinding medium in the mill repeatedly impacts and grinds the material by virtue of the kinetic energy obtained when the mill rotates. The crushed material is discharged into the suction tank through the tail of the ball mill, and then transported to the classifier for classification by negative pressure. The qualified fine powder is collected by cyclone collector or dust collector, The coarse particles after classification are discharged from the lower end of the classifier, and then re-enter the ball mill for crushing through the feeding pipe.

Note: The production capacity is closely related to the particle size, specific gravity, hardness, moisture and other indicators of the raw materials. The above parameters are for reference only, please consult our engineers for details.

Function : The electronic Ears senses the noise of the mill. The Ear consist of a very sensitive microphone installed at the mill inlet, at the grinding ball impact point, and as close as possible to the mill shell. The foam of the Electronic Ear must nearly touch the mill shell between two rows of bolts. The head of the micropone is 4-5 cm in the rear, and is protected by a fine grid covered by a thin plastic film at the level of the foam coat. Therefore, fitted in foam, the microphone is insulated from the interfering noises existing in the plant. The front cover prevents the entrance of dust, the accumulation of which would disturb the response of the Electronic Ear.

The heart of the electronic ear HASLER becomes digital and allows accurate measurement. The New Sound2 allows you to filter the sound to gain acuracy. From now on the calibration is automatic during the commisionning with the SOUND2. The filling level is displayed on the LCD screen. The digital outputs are configurable by the user.
